Description

Technical Field

[0001] The utility model relates to the technical field of automobile component processing, in particular to a low-pressure injection molding fabric turn-up device. Background Art

[0002] In addition to metal components, automobiles also include plastic interior trims, which enhance the visible surfaces of the interior and improve the driving experience. Furthermore, as people's expectations for the quality of automotive interiors continue to rise, most car interiors are made of suede-like materials. To improve the quality of suede-like fabrics, the industry uses low-pressure injection molding. Therefore, it can be assumed that low-pressure injection molded fabrics are commonly used in the interior trims of modern automobiles.

[0003] Currently, the processing process for low-pressure injection molded fabrics on the market typically involves closing the mold, injecting the raw material into the mold at low pressure using an injection molding machine, and then opening the mold to remove the product after molding. This process leaves excess fabric at the edges of the removed product, which needs to be removed in subsequent steps. The industry typically uses handheld tools to manually trim the excess material. While manual trimming is acceptable for small products, it can be inefficient, result in unevenly smooth edges, and cause burrs. Furthermore, for large, redundant products, in addition to the aforementioned issues, the trimming process requires frequent adjustments to the product's position and orientation, which is labor-intensive, time-consuming, and labor-intensive. Therefore, the industry has gradually adopted a reverse hemming method, where the appropriate edges are folded back and welded together using a welding head. This improves edge smoothness and reduces burrs. Although the above process solves the problems of uneven cutting edges and burrs caused by manual cutting, it still relies on manual operation of the welding head for spot welding. In addition, the spot welding is performed while the edge is reversed, which increases the difficulty of operation and low efficiency. It is also easy to cause the front and rear edge misalignment, affecting product quality. Summary of the Invention

[0029] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the following embodiments are combined with the attached Figure 1 To the attached Figure 6 The technical solution provided by the present invention is described in detail, but the following content is not intended to limit the present invention.

[0030] Figure 1 This is a structural diagram of an embodiment of a low-pressure injection molding fabric turn-up device of the present utility model; Figure 2 This is a structural diagram of a low-pressure injection molding fabric turn-up device of the utility model after the outer panel is opened. Figure 1 and Figure 2 As shown, the low-pressure injection molding fabric turn-up equipment provided in this embodiment includes: a frame 1, a welding machine 2, a rotating table 3, and a bottom mold fixture 4, a clamping component 5, and a pushing component 6 installed on the rotating table 3.

[0031] Specifically, a welder 2 is mounted at one end of the frame 1. A welding head 21 is mounted on the welder 2, which spot welds the reversed low-pressure injection molded fabric to meet processing requirements. Furthermore, a rotating table 3 is positioned at the other end of the frame 1. As the rotating table 3 rotates, the low-pressure injection molded fabric to be spot welded on the rotating table 3 passes through the welder 2 in sequence, meeting the spot welding requirements.

[0032] Figure 3 This is a schematic diagram of the installation of a rotating table, a pressing assembly and an edge pushing assembly in a preferred embodiment of the present invention. Figures 1 to 3As shown, two bottom mold jigs 4 are symmetrically arranged on the rotating table 3 with its own rotation axis as the center, so that every time the rotating table 3 rotates 180°, the two bottom mold jigs 4 can swap positions with each other, thereby meeting the processing requirements of one bottom mold jig 4 for spot welding and the other bottom mold jig 4 for loading and unloading. This can not only keep the loading and unloading area away from the spot welding area, thereby improving safety, but also meet the needs of loading and unloading while spot welding, and the processing efficiency is higher. In addition, when the rotating table 3 rotates, the two bottom mold jigs 4 alternately pass through the welding head 21 of the welding machine 2 to meet the spot welding requirements. At the same time, a number of clamping components 5 are provided on the rotating table 3 and located next to each bottom mold jig 4, and each clamping component 5 has a pressure head close to or away from the bottom mold jig 4. The pressure head of the clamping component 5 presses the main body of the low-pressure injection molding fabric placed in the bottom mold jig 4 to maintain the stability of the low-pressure injection molding fabric during the reverse packaging process. In addition, a plurality of edge-pushing assemblies 6 are provided on the rotating table 3 and located beside the bottom mold fixture 4. At this time, each edge-pushing assembly 6 includes an edge-pushing driver 61 and an edge-pushing block 62. In addition, the driving shaft of the edge-pushing driver 61 is arranged toward the corresponding bottom mold fixture 4 and performs telescopic movement away from or away from the corresponding bottom mold fixture 4. At the same time, the edge-pushing block 62 is installed on the driving shaft of the corresponding edge-pushing driver 61, so that the edge-pushing driver 61 can drive the corresponding edge-pushing to approach or move away from the bottom mold fixture 4. That is, when the low-pressure injection molding fabric to be reversed is placed in the corresponding bottom mold fixture 4, it can be pressed by the pressure head of the clamping assembly 5, and the edge-pushing driver 61 pushes the push block toward one side of the bottom mold fixture 4. The edge of the low-pressure injection molding fabric is folded by the push block to achieve reverse packaging, which provides conditions for the subsequent spot welding of the welding head 21. In addition, the entire process is implemented based on a mechanical structure, without the need for manual intervention, and the unified reverse packaging standard improves product quality. At the same time, it also improves processing efficiency and saves more labor and effort.

[0033] More specifically, a middle partition 7 is provided on the rotating table 3 and between the two bottom mold fixtures 4. The middle partition 7 separates the two bottom mold fixtures 4 on the rotating table 3, that is, separates the loading and unloading area and the spot welding area, which provides higher safety assurance.

[0034] More specifically, the middle partition 7 is arranged in a split manner. In this case, the middle partition 7 is divided into a fixed partition 71 and a movable partition 72. The movable partition 72 is installed on the turntable 3 so that the movable partition 72 can rotate with the turntable 3, while the fixed partition 71 is arranged above the movable partition 72 and fixedly installed on the frame 1. In this way, the weight of the middle partition 7 used for protection can be distributed between the turntable 3 and the frame 1. While meeting the same protection area size, it can effectively reduce the burden on the turntable 3 and make the structural design more reasonable. Preferably, the fixed partition 71 is a mesh structure, which can not only provide protection, but also facilitate observation by operators and achieve ventilation and heat dissipation.

[0035] More specifically, the rotating platform 3 comprises a rotary actuator 31 and a tabletop 32. During installation, the rotary actuator 31 is mounted on the frame 1, ensuring stable mounting of the rotary actuator 31 on the frame 1. Furthermore, the tabletop 32 is a frame structure and is arranged horizontally, providing a large loading surface while reducing the platform's weight. Furthermore, the center of the bottom of the tabletop 32 is mounted on the drive shaft of the rotary actuator 31, maintaining both load and operational stability of the tabletop 32 and enabling rotation under the action of the rotary actuator 31.

[0036] Figure 4 This is a structural diagram of a preferred embodiment of the present invention, in which a mold changing and ejecting assembly is installed on the rotating table. Figures 1 to 4 As shown, the turntable 3 also includes two sets of mold-changing ejector assemblies 33. Each set of mold-changing ejector assemblies 33 corresponds to a base mold fixture 4. This allows a base mold fixture 4 to be lifted up by the corresponding set of mold-changing ejector assemblies, facilitating replacement and repair of the base mold fixture 4. Furthermore, each set of mold-changing ejector assemblies 33 includes several ejector glides. During installation, the ejector glides of the same set are spaced apart along the length of the base mold fixture 4, allowing different positions of the base mold fixture 4 to correspond to different ejector glides, maintaining stability when the base mold fixture 4 is lifted. Furthermore, each ejector glides includes a base frame 331, a lifting plate 332, an ejector driver 333, and several wheels 334. During installation, the base frame 331 is mounted to the bottom of the tabletop 32, and several ejector drivers 333 are mounted on the base frame 331. This allows the base frame 331 to serve as a carrier for the ejector drivers 333 to be mounted on the tabletop 32, enhancing operational efficiency. Furthermore, the bottom of the lift plate 332 is connected to the drive shafts of several ejection drivers 333 mounted on the corresponding base frame 331, so that when the ejection drivers 333 are in operation, they can drive the lift plate 332 to rise and fall. Simultaneously, several wheels 334 are provided on the lift plate 332, so that when the lift plate 332 is raised or lowered, the wheels 334 can also rise or fall. Specifically, when the wheels 334 rise, they contact the bottom mold fixture 4 and lift it, separating it from the table 32. This facilitates the operator to push and pull the bottom mold fixture 4 by means of the rolling motion of the wheels 334, thereby meeting the need for quick replacement and maintenance of the bottom mold fixture 4. Preferably, the wheels 334 are bull's-eye wheels, which can achieve universal rotation, thereby adapting to support and movement requirements in different directions, facilitating mold changes and maintenance operations for the operator, and saving time and effort.

[0037] Figure 5 This is a structural diagram of a preferred embodiment of the present invention, in which the pressing assembly and the edge pushing assembly are installed on the mold plate. Figure 2 、 Figure 3 as well as Figure 5As shown, each bottom mold fixture 4 corresponds to a mold plate 41. At this time, the mold plate 41 is installed horizontally on the table 32. At the same time, the multiple clamping components 5 and multiple pushing components 6 corresponding to the bottom mold fixture 4 are installed on the mold plate 41 where the bottom mold fixture 4 is located. That is, the bottom mold fixture 4 and the corresponding clamping components 5 and pushing components 6 can form an integral structure through the mold plate 41, which is convenient for subsequent unified replacement according to different product models, making operation more convenient. At the same time, a number of clamping components 321 are provided on the table 32. At this time, the corresponding mold plate 41 is clamped or loosened by the clamping components 321. That is, during normal use, the mold plate 41 can be clamped by the clamping components 321, thereby achieving the fixation of the bottom mold fixture 4, the clamping components 5 and the pushing components 6. When replacement or maintenance is required, the mold plate 41 can be loosened by the clamping components 321, facilitating the replacement or maintenance of the integral structure composed of the bottom mold fixture 4, the clamping components 5 and the pushing components 6. Preferably, several locking assemblies 321 and several pressing assemblies 5 all include a rotating cylinder, a deflection frame and a pressure frame. The rotating shaft of the rotating cylinder is connected to one end of the deflection frame, so that the rotating cylinder can drive the deflection frame to deflect, and the pressure frame is installed at the other end of the deflection frame. When in use, the deflection frame is driven to deflect by the rotating cylinder, and then the pressure frame is driven to move by the deflection frame, so that the pressure frame can tighten or loosen the corresponding structure to meet the use requirements of tightening and locking and loosening and unlocking.

[0038] Figure 6 This is a schematic diagram of the installation of the bottom matching component of a preferred embodiment of the utility model. Figure 2 and Figure 6As shown, a bottom mating assembly 8 is provided between the frame 1 and the rotating table 3. Furthermore, the bottom mating assembly 8 comprises a mating adjustment frame 81, a roller 82, and a mating block 83. During installation, the mating adjustment frame 81 is mounted on the frame 1 with one end extending toward the bottom of the table 32. The roller 82 is mounted on the end of the mating adjustment frame 81 extending toward the table 32, so that the roller 82 is positioned near the bottom of the table 32. At the same time, a mating block 83 is also provided at the bottom of the table 32. The mating block 83 protrudes from the bottom surface of the table 32, and when the table 32 rotates, the mating block 83 passes through the roller 82 and contacts the roller 82. That is, after the rotary table 3 rotates to a predetermined position, the table 32 can be supported by the contact between the roller 82 and the mating block 83. In addition to being supported by the rotary drive 31 during loading and unloading and spot welding, the table 32 can also be supported by the bottom mating assembly 8 to maintain the stability of the table 32 during loading and unloading and spot welding, thereby ensuring product quality. In addition, as the table 32 continues to rotate, the mating block 83 separates from the roller 82. At this time, there is a gap between the roller 82 and the bottom surface of the table 32, which will not hinder the rotation of the table 32, ensuring that the table 32 can rotate smoothly. Preferably, the matching adjustment frame 81 includes a vertical frame and an adjustment plate. During installation, the vertical frame is fixedly installed on the frame 1. An adjustment plate is provided on the vertical frame. Two angular holes are provided on the adjustment plate in the vertical direction. Each angular hole is provided with an adjustment screw connected to the vertical frame. In addition, the roller 82 is installed on the adjustment plate. The height of the adjustment plate can be adjusted by loosening or tightening the adjustment screw, thereby adjusting the height of the roller 82, which provides conditions for subsequent adjustment of the contact force between the roller 82 and the matching block 83, thereby adapting to the processing requirements of different products.

[0039] More specifically, the welding machine 2 includes a plurality of operators 22. At this time, the plurality of operators 22 are arranged at intervals on the frame 1, which can realize zoned spot welding and improve processing efficiency. In addition, the operator 22 selects a multi-axis robotic arm, which can realize multi-directional and multi-angle spot welding, and the structure is more flexible, thereby adapting to the reverse spot welding requirements of irregularly shaped low-pressure injection molded fabrics. At the same time, a welding head library 23 is also provided on the frame 1 and located between two adjacent operators 22, and a plurality of different types of welding heads 21 are placed in the welding head library 23, so that when spot welding different positions of the same product or spot welding products of different specifications is performed subsequently, the appropriate welding head 21 can be selected from the welding head library 23 according to the needs and installed on the corresponding operator 22, which has better adaptability.

[0040] More specifically, an outer panel 9 is provided on the frame 1, located outside the welding machine 2 and the rotary table 3. The outer panel 9 surrounds the welding machine 2 and the rotary table 3, providing external protection and further enhancing safety. In addition, a loading and unloading window 91 is provided on the outer panel 9, located on the side of the rotary table 3 facing away from the welding machine 2, to facilitate the operator to load and unload the rotary table 3. At the same time, an inspection door 92 is provided on the side of the outer panel 9, located near the end of the welding machine 2, to facilitate observation of the working status of the welding machine 2 and to facilitate subsequent maintenance of the welding machine 2 and its related structures.

[0041] More specifically, a safety grating 93 is provided on the outer enclosure 9 and on both sides of the loading and unloading window 91. The safety grating 93 can detect whether there are foreign objects in the loading and unloading window 91, thereby avoiding safety hazards caused by accidental rotation of the turntable 3 during the loading and unloading process, and further improving the safety of the equipment.

Each guide plate is provided with a plurality of rollers at intervals along its length direction, so that when replacing or repairing the overall structure composed of the mold plate 41, the bottom mold fixture 4, the clamping assembly 5 and the push edge assembly 6, the relative rolling of the side of the mold plate 41 by the rollers can guide the movement of the mold plate 41, meeting the use requirements of rapid replacement and making the structural design more reasonable. Preferably, the rollers are bearings, which can better meet the rolling requirements and can be directly purchased and installed, which is lower in cost.

[0043] The low-pressure injection molding fabric reverse packaging equipment provided in this embodiment includes a frame 1, a welding machine 2 and a rotating table 3; by respectively arranging the welding machine 2 and the rotating table 3 at both ends of the frame 1, and symmetrically arranging two bottom mold fixtures 4 on the rotating table 3, and each bottom mold fixture 4 corresponds to a number of clamping components 5 and pushing components 6, the low-pressure injection molding fabric to be reversed is pressed by the clamping component 5, and the side of the low-pressure injection molding fabric is pushed to be folded by the pushing component 6, and then it is rotated to the welding machine 2 through the rotating table 3, and the folded side is spot-welded by the welding head 21 of the welding machine 2 to realize the reverse packaging processing, and no manual operation is required during the reverse packaging and spot welding process, which is more time-saving and labor-saving.
